Exhibition in Helsinki As the copyright geek I am, this week I’m celebrating the public domain with a small exhibition at Katugalleria Mutteri in Sturenkatu, Helsinki, Finland, featuring various public domain items. The exhibition goes on from 2023-03-17 to 2023-03-24 at 8:00 in the morning. The purpose of the exhibition is to advertise the sale of a lovingly used copy of a Ravensburger 15250 1000-pieces puzzle, featuring a drawing of the Uomo Vitruviano by Leonardo da Vinci.
